We spent one week at Sina’s place and everything was as described. It was clean, vey comfortable and fairly quiet. The apartment does overlook a construction site so there could be a bit of noise from that during your stay. We didn’t find it too disturbing while doing work from the apartment during the day though.
There’s a big supermarket just next to the apartment complex that has everything you need and Ramkhamhaeng station isn’t too far of a walk if you need to get to the center of the city.
Good value and would happily stay here again.
